20. Health Conditions Affecting Purring
Certain medical conditions can alter or inhibit a cat’s ability to purr. Laryngeal paralysis and respiratory diseases may affect the vocal cords or muscles involved in purring, leading to changes in sound or complete absence of the purr (Merck Veterinary Manual). If your cat’s purr seems different or disappears, it’s wise to consult a veterinarian to rule out underlying health issues.
